GLASS-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent N O. 706,550, datdAugust12, 1902.

Application filed September 16, 1901. Serial No. 75,563. (No model.)

.To all whom, t weary concern.:

E@ it known than, HENRY` contines, a @itii zen of the United States,residing at Oak Sta- My invention is an improvement in glass:

making machines, and relates particularly to that class forrolling themolten mass of material into flat plates of glass of any desired widths.p

The object'ofmy invention is to provide a machine by which theglassisfiattened out by a series of rollerswhich are tempered andregulated to suit the condition and state of the molten glass; andanother object is to provide the roller with a suitable covering thatshall prevent to the smallest degree the roughness or defects of the`glass so com mon to machines now generally used.

A further object of my invention is to provide an arrangement of pipefor feeding steam or hot or cold water to the cylinder forregulatin gthe temperature thereof; and with these objects in'vie'w myf inventionconsistsin the peculiar construction and novel combination andarrangement of` parts, aswill be fully de-f scribed in the followingspecification, reference being hadto the drawings, in which- Figure l isa side elevation of myimprovement, one set of gearwheels-being removedand shown in dotted outlines for the purpose of showing thebearing-boxes. Fig. 2 is an end View of the machine. Fig. 3 is averticalcentral section. Y taken through one pairof cylinders. Fig.` 5 is adetail section taken about on Vthe line 5 5 of Fig. 4. i

In constructing a machine .in accordance with my invention I employ aframe A, con-l sisting of two side plates A A, suitably mounted uponsills A? A2 and held together by stay-bolts A3 A3, cach plate having itsopposite vertical edges provided with. a series of raceways or slots act a, in which are slidably held journal-boxes B, having shafts B heldtherein, upon each of which is mounted a hollow cylinder C. Thesecylinders form an import-ant feature of my invention, each consisting ofan outer shell C', having flanges C2 C2 arranged at the ends thereof,and with shown.

Fig. 4. isa horizontal section .inders are closed andmade `steam orwater tight by means of end plates C5 C5, and as the cylinders are madein pairs-thatis, two cylinders being arranged` upon the same horizontalplanethe plates of one cylinder of each pair are extended past itsperiphery and overlap the sides of the opposite cylinder, as shown atC6C6, and as the cylindersare arranged a slight distance apart it Willbereadily seen that the 4ends of thespace areclosed by the saidoverlappingportionsCG C6. Each cylinder also has its periphery coveredvwith a thin `layer of aluminium, asshow'in at O7 C7, for the purpose ofpreventing the collection of foreign matter, such as rust, dec.

The shaft of each cylinder is provided at its ends with a bore B2 BS,which communicates with its cylinder and forms an inlet and exhaustport, respectively, to and` from the cylinders. The ends of the shaftshaving the bore B2 are provided with stuffingboxes B4, through whichisprojected the end of an inlet .pipe ornozzleiD, whose outer end isconnected to a 'l'.-jointhaving a steam and water pipe D D?. connectedthereto, each of which being provided with a valve d d2, as

By connecting thecylinder with the water and steam pipes I am enabled toquickly regulate the temperature of the cylinder whenever required,andshould they betooihot the valve'd' in the steam-pipe .is` turned oii,

`closing the inlet of steam, and the valve d2 in the cold water opened,which allows asufpply of cold water to enter the cylinders until thetemperatureis reduced. It will thus be seen that I provide avery simpleand economical arrangement of pipes wherein Iamntilizing one pipeforconducting the steam and hot water direct to the cylinders.

In order to adjust'thecylinders laterally to regulate the width ofthespace between each pair, I arrange in each racway a block E, having athreaded aperture earranged cen trally therein, in which'is designedtoo-perate the threaded end ofia boltF, that bears against thejournal-box B, and in order to hold these blocks against lateralmovement I provide each with pawls f j', that engage IOO wheels H H',which mesh with idlers J J, heldv upon stub-shafts J' J', secured to theframeplate A', the lowermost idler meshing with pinions K K' on thelower shafts B'.

A hopper L is positioned in the upper end of the frame and has its innerface lined with fire-brick L', as shown.

From the foregoing description it will be readily seen that I provide avery simple and economical form of sheet-glass-forming machine, and byreason of having the steam and cold-water pipes terminating in onecommon pipe the rotation of thev cylinders is not impaired and thetemperature of the cylinders may be regulated by regulating either ofthe stop-cocks. n

It may be stated here that I prefer to arrange the inlet end of theshafts with studing-boxes to prevent the escape of steam, and inpractice I also intend to provide one of the lower cylinders with acutting edge OXfor the purpose of severing the sheet of glass as itleaves the machine, and thus deliver it in plates or sheets of evenlength.

Having thus fully described my invention, what I claim as new, anddesire tosecure by Letters Patent, is-

1. In a glass-making machine, the combination of a frame composed of theside plates, each of which having slots or raceways arranged in theedges thereof, the said slots hav- ,ing ratchet-teeth formed'therein,boxes arranged in the said slots and having shafts journaled therein,cylinders held upon said shafts, blocks carrying pawls that are adaptedfor engagement with the said ratchet-teeth, and a screw operating in thesaid blocksand adapted to engage the said boxes whereby the saidcylinders may be adj usted laterally, and means for revolving the saidcylinders, substantially as shown and described.

upon the inner and outer edges thereof, boxes arranged in the saidslots, shafts journaled in the boxes, cylinders held upon the shafts andarranged in pairs in the frame, one cylinder of each pair havingendplates that overlap the ends of the opposite cylinder, therebyproducing a slot between the cylinders, blocks arranged in the groovesand having pawls for engagement with the ratchet-teeth, screws operatingwithin the blocks and adapted to bear against the boxes, whereby thewidth of the slot between the cylinders may be increased ordecreased,the said shafts of the cylinders having ports arrangedtherein, and one end provided with stuffing-boxes through which passpipes, gears mounted upon the opposite ends of the shafts, and idlersjournaled in the frame and adapted to mesh with the gears of the Shafts,and means for revolving the cylinders, substantially as shown and forthe purpose set forth.
